What has always worked for my Dad and I in the Rem 1100's is a white graphite,Dad an avid bird hunter (Quail) bought his first 1100 the year they came out 1963.He ran into problems in the colder months with oil lubes they would get cold and gum up,after switching to the white graphite no problems with the 1100 cycling in freezing temps.
The reason he used white graphite?
He first used regular black graphite after a full day out in the field he would have black graphite all over his hands and face even the white short haired pointers had black heads from Dad petting them LOL
